## @file gstlal_inspiral_marginalize_likelihoods_online
#
# This program runs gstlal_inspiral_marginalize_likelihood in a while True
# loop; See gstlal_inspiral_marginalize_likelihoods_online for more details
#
#
# This program is not meant to be executed standalone by a user. It should be
# part of a DAG managing a running gstlal_inspiral online analysis.
#
# This program takes two or more arguments;
#
# - The path of the output file name
# - One or more root URLs of the web servers from which to retrieve event
#   parameter distribution data (e.g., "http://node001.ligo.caltech.edu")
#
# This program queries each running gstlal_inspiral job via the URL,
# computes PDFs of the likelihood ratio ranking statistics from the
# parameter distribution data, then marginalizes the ranking statistic PDFs
# across jobs and writes the result to the given output file.
#
# It continues to do that in an infinite loop with a 10 minute pause on
# each iteration.  Files are not overwritten directly, but rather via a
# temporary file and mv operation to ensure that no files are corrupted in
# a POSIX file environment.
# 

#
# get the output file name
#
